When do you think is the appropriate age for my baby to eat outside food? Please share your own experiences on what kind of outside food you gave

I gave my kids to taste outside food after they turned 2 years old. Before that I will prepare my own food/snacks. After 2 years old, I normally ask the restaurant to reduce salt for my baby's dishes. The first outside food my kids get to taste is Udon soup at Japanese restaurant. Normally, I will order light soup based noodles e.g. bee hon soup and etc. when they are young.
